Abstract or Description

Past research demonstrates that unconscious primes can affect people’s decisions. However, these free choice priming paradigms present participants with very few alternatives. Magicians’ forcing techniques provide a powerful tool to investigate how natural implicit primes can unconsciously influence decisions with multiple alternatives. We used video and live performances of the Mental Priming Force. This technique uses subtle non-verbal and verbal conversational primes to influence spectators to choose the three of Diamonds. Our results show that a large number of participants chose the target card while reporting feeling free and in control of their choice. Even when they were influenced by the primes, participants typically failed to give the reason for their choice. These results show that naturally embedding primes within a person’s speech and gestures effectively influenced people’s decision making. This raises the possibility that this form of mind control could be used to effectively manipulate other mental processes.
